Improve generating Custom entry function

Browse source 
This commit is aimed at making compiler generated entry functions
(Basically just C `main` right now) more generic so other targets can do
similar things for custom entry. This was initially implemented as part
of https://github.com/rust-lang/rust/pull/100316.

Currently, this moves the entry function name and Call convention to the
target spec.
